Problems solved by technology

Whether it is a single linear grain or a flat grain, the air supply time of these grains is very short due to the limitation of the extended plane size
For example, the working time of a generator made of a single solid nitrogen charge is generally up to 20 minutes. Even if it is made into a flat-layer curved charge as described in the patent CN205820891U, it is difficult to double it when the human body is easy to carry. operating hours
The space utilization rate is not high, and the grain column is too high and too long, which is not conducive to the miniaturization of the assembled generator

Embodiment 1

[0038] figure 1 It is a cross-sectional view of a generator in two directions, showing an embodiment of a stacked nitrogen generator according to the present invention. As shown in the figure, the nitrogen generator includes a generator housing 1 and a generator upper cover 13, wherein the generator housing 1 is in the shape of a rectangular cylinder with rounded corners, the bottom is closed, the upper opening is open, and the inner part of the chamber is used as a combustion chamber. chamber and filled with nitrogen tablets 5 and heat insulating material 8; the upper cover 13 of the generator is provided with three round holes, which are respectively used to install the ignition device, the pressure relief valve 14 and the flow regulating valve of the gas outlet 15, and the upper cover 13 of the generator is welded on the generator housing 1. The ignition device is connected with the generator upper cover 13 by welding.

[0039] The nitrogen generator also includes an igni...

Embodiment 2

[0053] figure 2 It shows an embodiment of a laminated nitrogen generator. In this embodiment, the nitrogen tablet is an M-shaped flat layer structure that is folded and bent from one end to the other end. In the nitrogen generator made in the above way, the trigger signal first triggers the igniter, and then the igniter ignites the connected grain, where the connected grain can be made into a kind of igniter, and then the tablet and the grain pass through in an orderly manner. Low-temperature, continuous low-flow combustion realizes long-term low-flow nitrogen supply, and the generated nitrogen is purified and cooled by the filter layer to obtain low-temperature, pure nitrogen, which is discharged through the gas outlet.

Abstract

The invention mainly provides a laminated nitrogen generator. The nitrogen generator is mainly characterized in that a nitrogen generating agent is pressed into curved disk-shaped tablets (hereinafter referred to as tablets), then the tablets are stacked through connecting drug columns to form a specific shape, and then nitrogen is released through continuous and orderly combustion. In order to ensure that the assembly type tablets are continuously and orderly combusted without causing crossing combustion, a certain gap is required between each layer of tablets, and the height of the gap can be adjusted through the connecting drug columns. Since the tablets are laminated assembly type, the size is small, the weight is light, and the generation of the nitrogen for a long time can be ensured.

Description

technical field [0001] The invention relates to a laminated nitrogen generator. More specifically, it relates to a nitrogen generator that uses a plurality of tablets pressed into a curved disk shape and is stacked by a plurality of connecting grain columns. [0002] technical background [0003] The nitrogen generator prepared by using the pyrolysis principle of nitrogen gas generating agent is mainly composed of starting device, nitrogen generating drug block and nitrogen filter material. The heat generated by the starting device decomposes the medicine block and releases nitrogen gas, which is purified by the internal filter material and then discharged from the outlet. [0004] In the past, the grains of the compressed grain type solid nitrogen generators were all single linear grains or curved plane grains. For example, a flexible oxygen candle generator described in patent CN205820891U uses a curved oxygen candle The main linear oxygen candles are connected continuous...
